Application example volume flow
In this example, a 12 inch (0.305 m) venturi flume is installed in an open channel.
According to the manufacturer's data sheet, the maximum nominal flow rate of the
device is 1143 m
3
per hour at a maximum level of 0.6 m. The SITRANS LR150 was
installed at a height of 1.6 m above the channel.
